e/Alusil

Information
has gloss	eng: Alusil as a hypereutectic aluminium-silicon alloy (AlSi17Cu4Mg) contains approximately 70% aluminium and 30% silicon. This alloy was created in 1927 by Schweizer & Fehrenbach of Baden-Baden Germany and further developed by Kolbenschmidt. Alusil, when etched, will expose a very hard silicon precipitate. The silicon surface is porous enough to hold oil, and is an excellent bearing surface. BMW switched from Nikasil-coated cylinder walls to Alusil in 1996 to eliminate the corrosion problems caused through the use of petrol/gasoline containing sulfur.
